22 Claims.

This invention relates to closure assemblies for ventilating areas in windows and in more particular to ventilating areas in metallic windows.

An object of this invention is to provide a closure provided with a flexible contact engaging the frame surrounding the closure.

Another object of this invention is to provide a closure for ventilating areas of windows that is cheap, eflicient, durable and dependable, that makes good contact so as to protect the interior of the building from the elements.

Another object of this invention is to provide a unitary structure for the closure and its screen that may be inserted as a unit into the ventilating area.

With the above primary and other incidental objects in view, as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation or their equivalents, as hereinafter described and set forth in the claims.

Fig. 1 is a sectional view taken substantially on the line ll of Figs. 2 and 4.

25 Fig. 2 is a sectional view taken substantially on the line Z-2 of Fig. 1.

Fig. 3 shows a vertical sectional view of another modification.

Fig. 4 is a fragmentary sectional view taken substantially on the line 4-4 of Figs. 1 and 2.

Fig. 5 is a profile View of the swinging element about the hinge shown in Fig. 2 with portions of the swinging element concealed by the basin-like sill shown by dotted lines.

This is a. divisional application of my copending application Serial No. 61,412 filed Jan. 29, 1936 for Flexible window closure.

Referring to the drawings, a plurality of transversely disposed T-shaped duo-functional muntin and detention bars 2!] divide the window into a plurality of spaces, some of which are glazed, as shown at 22, leaving a group of spaces 24 vacant.

The unglazed spaces 24 provide spaces for Ventilation. In order to protect the occupants of the building during inclement weather, it is desirable to provide a suitable closure for the vacant spaces 24-.

In the preferred embodiment, as shown in Figs. 1 and 2, the closure assembly includes a sheet metal frame located on the outside of the muntin bars. In this embodiment the frame is formed from flanged members 30 and 32 cooperating to form glazing channels 34 and weather stripping channels 36 projecting in a direction normal to the glazing. Suitable weather stripping members 38 are seated in the channels to secure weather tightness between the closure and the fixed portion of the window whenever the closure is moved into closed position.

This closure assembly is pivotally mounted upon pintles 46 passing through suitable apertures in members 30 and 32 and through the side flanges 42 of a basin-like sill member 44. The swinging element of the hinge portion constitutes member 30, best seen in Fig. 5, with the portions thereof concealed by the flange 42 of the basin-like sill member 44 shown by dotted lines. The sill 44 has been broken, so as to only show the portion adjacent the movable closure. In this figure the movable closure has been shown independently and away from the fixed portions of the window.

As best seen by referring to Fig. 2, the basinlike sill member 44 is provided with a retaining portion 46 contoured to fit snugly over the flange of the muntin bar extending across the bottom of the vacant spaces 24. This portion 46 holds the basin in. position by screws 41. In order to provide clearance for the muntin bar 29 extending across the vacant spaces 24 as a detention bar, the portion 46 has been notched at 48.

The flange 42 of the basin-like sill member 44 may be Welded or otherwise secured to the flanges of the vertical muntin bars 20 bounding the sides of the Vacant spaces 24. This gives rigidity to the sill member 44, which supports the weight of the movable closure assembly.

The movable closure may be held in closed position by a latch 50 pivotally mounted at 52 to member 30 and adapted to engage a suitable catch 54. Suitable stops or links not shown may be used to limit the opening of the closure.

In addition to the movable closure, it is sometimes preferably toprovide a screen extending over the vacant spaces, serving a dual purpose in detention windows. It prevents the free ingress and egress of live bodies, as well as inanimate bodies such as implements, sought by inmates for effecting an escape, and it serves as a tell-tale in the event attempts are made to sever the detention bars extending over the ventilating area so as to escape therethrough.

The screen disclosed in Figs. 1 and 2 includes a wire mesh screen Ell attached to substantially rectangular members 62 extending along the vertical sides and the top of the screen 69 and a substantially inverted L-shaped member 64. Members 62 contact the flanges of the muntin bars 29 bounding the ventilating area. Member 64 extends across the basin-like sill member 44 and forms a clearance for the bottom of the movable closure. Weep holes 68 provide drainage ducts for rain and condensation tending to accumulate in the basin-like member 44.

The screen is mounted in a cavity between the closure frame and the muntin bars 26 bounding the ventilating area.

Referring to the modification disclosed in Fig. 3, the closure and screen assembly have been mounted so as to be partially enclosed by the stems of the muntin bars 20. In this modification the movable closure it includes a frame in cluding members 12 substantially L-shaped in cross sectional area. The closure it is pivotally attached by hinges l4, only one of which is shown, to the web of the muntin bar 20 extending across the bottom of the ventilating area. The closure is held in closed position by a suit able latch 16 in a manner similar to that de scribed in connection with the modification shown in Figs. 1 and 2.

The closure assembly 88, which has been shown as a screen, projects through the ventilating area. The screen frame is formed from angle bars having the flanges 92 projecting through the ventilating area and supporting the screen 94 suitably attached thereto. An abutment or snubber 96 attached to the lower flange 92 holds the screen frame at a proper height. A stop 9! is arranged in hooked relation with the flange of the detention bar 20 to prevent the screen frame from removal bodily inwardly. The upper flange is held in position by a diagonally arranged screw 98.

Although the preferred modification of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts which generally stated consist in a device capable of carrying out the objects set forth, in the novel parts, combination of parts and mode of operation, as disclosed and defined in the appended claims.
